 Manisha said: (Oct 1, 2014) Why we have divided here with 7.88?

 Ammish said: (Jul 14, 2015) Was wondering same why dividing by 7.88 not 5.01?

 Bulupadhee said: (Jun 9, 2016) Because it has asked for by what percent it is less. So here the formula would be, => ((Big value - Small Value) / Small value) * 100. If this is the case where it was asked by what percent it is greater, the answer might have been, => (7.88 - 5.01 / 5.01) * 100.

 Jain said: (Jun 15, 2019) Because it is written what percent less than shampoo so we took it in the denominator.

 Darsh said: (Aug 21, 2019) Right, Agree @Jain.

 Riva said: (Jul 30, 2021) According to me, the calculation done is wrong, the method and the numbers selected are correct but the correct answer is 57% and not 36%. I have cross-checked and done the calculation more than once. Someone, please verify as well.

 Jigme said: (Aug 16, 2021) 7.88 - 5.01=12.89. 12.89/5.01 * 100= 57.

 Korphu said: (Aug 31, 2021) @Jigme. How come 12.89? Explain.
